Digital Waveform Names

Chris over at the Yahoo group posted this nice bit of info regarding the names of some of the digital waveforms in the Evolver. As most of you probably know, the digital waveforms in the Evolver are the same as those in the Prophet VS. Anyway, I thought I'd repost it here for additional safekeeping, and to see if anyone else has additional info on the waveforms. Having a *complete* list of names/descriptions of the waveforms would be awesome. Thanks Chris! Read on...

Subject: Digital Waveform Types

Hello,
I've been curious as to the types/names of the waveforms that the digital oscs use in the Evolver. I found a Prophet-VS manual and transcribed its waveform list over to the corresponding Evolver wave #'s. These are the only ones listed in the VS manual (the rest of the names are apparently veiled in mystery.)

# NAME/DESCRIPTION

01 Sine
02 Sawtooth
03 Square
14 Pulse var1
15 Pulse var2
25 3rd and 5th harmonics *fundamental absent
27 Heavy 7th harmonics
29 BASSBELL 14th and 28th harmonics
44 VOCAL1 *Detune oscillators using either waveform to bring out the vocal quality
45 VOCAL2 *Detune oscillators using either waveform to bring out the vocal quality
82 Bell Partials1
84 Sawtooth 3rd and 5th
85 Sine 5ths *2 sines an octave and a 5th apart
86 Sine 2 Octave *2 sines, 2 octaves apart
87 Sine 4 Octave *2 sines, 4 Ocataves apart
88 Sawtooth 5ths *2 saws, an octave and a 5th apart
89 Sawtooth 2-Octaves *2 saws, 2 octaves apart
90 Square 5ths *2 squares, a 5th apart
91 Square Octave+5th *2 squares, an octave and a 5th apart
92 Square 2-Octaves *2 squares, 2 octaves apart
94 Bell Partials2
95 Blank Wave

Hi list!

I just wandered over to see the chat on Dave's new synth, and found this page about the VS waveshape names. Since it was my job to create most of the original waveshapes with the special program that Josh Jeffe wrote (called "Hacker"), I thought I'd make some comments, since you were looking for more details.

Firstly, the initial list you posted of just a few VS waveshape names is pretty much all of the names I originally made up (expect the numbering is off, of course). The reason so few were named is, most of these waveshapes had no "rhyme or reason" to them; I just moved a mouse around in the waveshape window of Hacker, and stored them when I liked what I heard....so, unfortunately there is no "mystery" about the sources - just a completely empirical approach, you might say.
I have no idea where that "complete list" of names came from - someone's attempt to identify for easier use, I guess. (Ravi's idea that "This tells me perhaps that other than the first short list, the longer list may be somewhat unofficially manufactured after the fact" is indeed the case.)

The names that I did put in the VS manual attempted to describe the waveshapes when there was some logic to it, such as 2 saws tuned an octave or a fifth apart, etc. A couple of the waves were taken from a sample of Josh's voice, while a few others were visually 'copied' from the front panel silk-screen of a Korg DW6000 . The wave drawing program also had an additive synthesis function where I could set the level for each of 16 harmonics, and the silk-screen of the Korg had several waveforms printed in this "harmonic drawbar" fashion...so, I just eyeballed the levels, and counted across the 16 lines to "copy" the waveshapes. I was as surprised as anyone to find that it produced a pretty close approximation (Korg must have done a good job on those screened
graphics!).

I think the most fun of all was creating original waveshapes from the VS itself. As Chris Meyer says, this aspect of the VS was usually sadly negelected.

All in all, a unique-sounding beast!

Cheers,
John Bowen

Thanks for the history, John. Quite interesting. I especially like the part about the visual "copying" from the front panel on the DW6000! In the past, I've read a bit about Josh's and your efforts on the VS, but I'd never heard that one before.

Do you guys still have a copy of Josh's "Hacker"? If so, what format is the data output - is it in the "Packed MIDI Data" (as Dave likes to call it in the Evolver manual) format? I was working on a conversion utility myself (as mentioned in another thread in this forum), and so is at least one other Evolver owner. If you still have it, and are OK with sharing it, the source code - or even just the executable - of Hacker might be of great help.

Thanks again for the info and history. Do you have an Evolver yourself yet?


BTW, the thread regarding the loading of user waveshapes into the Evolver is here:

Hi Ski,
No, there's nothing of 'Hacker' around that I know of...and it would be technically part of Yamaha's intellectual property now, since they purchased Sequential at the end of 1987.

Regards,
John B.

P.S. no, I don't have an Evolver yet

Thanks John. Good point regarding the ownership... I should have thought of that before opening my mouth! Hopefully, "Hacker" hasn't been lost over the years, which would be a shame.

BTW, given that you don't have an Evolver, how did you ever come across this forum?!
